Email local part

The module table.email_localpart extracts and unescapes local ("username") part of the email address.

E.g.

• test@example.org => test
• "test @ a"@example.org => test @ a

Mappings for invalid emails are not defined (will be treated as non-existing values).

table.email_localpart { }

table.email_localpart_optional works the same, but returns non-email strings as is. This can be used if you want to accept both user@example.org and user somewhere and treat it the same.
